CORN-PLANTER.

SPECIFICATION forming part of Letters Patent N 0. 456,548, dated July28, 1891.

Application filed March 21, 1891. Serial No. 385.845; (No model.)

To aZZ whom it 72mg) concern.-

Be it known that I, CLIFFORD J. BROWN, a citizen of the United States,residing at La Grange,in the county of La Grange and State of Indiana,have invented certain new and useful Improvements in Corn-Planters; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention has relation to an improvement in corn-planters, and thenovelty will be fully understood from the following description andclaims, when taken in connection with the accompanying drawings, inwhich Figure 1 is a plan view of my improved machine. Fig. 2 is a sideelevation of the same. Fig. 3 is a transverse sectional view taken inthe plane indicated by the dotted line w w of Fig. 1; and Fig. 4 is across-sectional view of the shaft and reciprocating arm,taken at thepoint indicated by the dotted line y 3 on Fig. 1.

Referring byletter to said drawings, A indicates the rear main frame ofmyimproved machine. This frame is preferably of a rectangular form andis mounted upon an axle B, carrying supporting-wheels C, and said framealso carries the drivers seat D, all of which may be of any ordinary orapproved construction.

E indicates the front section of the main frame. This front sectioncarries the usual furrow-openers and seed-boxes, as shown, and isconnected with the forward end of the rear section A in a hinged manner,as will be presently described.

F indicates castings, which are provided with a vertically-disposedrectangular loop or openingo and are secured by a branch I) to theforward ends of the lateral beams c of the rear frame A, and saidcastings have a hinge or pivot-lug cl, through the medium of which andbyascrew-bolt or the like and the employment of a shackle or clip G saidcastings are flexibly connected or hinged to the transverse beam e ofthe forward frame or section E. It will thus be seen that the forwardsection of the main frame is connected with the forward portion of therear section of said frame, so that said sections may be a1- lowed tomove in a hinged manner and vertically with respect to each other.

Arranged in the vertical loops or openings aof the castings F are boxesf, which furnish bearings for the rod or shaft H, which carries at itsopposite ends in a fixed manner the driving-wheels I. These boxes areprovided with suitable guide-flanges, which partly embrace the verticalbranches of the loops a and are designed to move vertically therein.

J indicates a hollow shaft placed over the solid shaft or rod II. Thishollow shaft J has one end terminating at a pointabout the center of themain frame, and its opposite end is suitably fixed in one of thevertically-movable bearings for the wheel-shaft, and said hollow shaft,while being allowed a vertical movement with the shaft H, is preventedfrom rotating therewith by reason of it being fixed with respect to oneof the bearings in the looped castings. This hollow shaft J is providedat its inner end with external screw threads 5 to receive aninternallythreaded sleeve or ring K, and this latter sleeve or ring K isprovided at diametricallyopposite points with screw-tapped holes 71. toreceive pivot-screws for a cam-ring, as will be presently explained. Theouter end of this hollow shaft may be squared or made fiat-sided toenter the hearing or box of one of the looped castings, although saidshaft may be constructed in any suitable manner to prevent it fromrotating with the shaft H, the object of which will presently appear.

L indicates a disk, which may have a collar t' and a vertically disposedperipheral flange it. This disk is secured to the shaft H at a pointadjacent to the inner end of the hollow shaft .I and carries on one sideof the flange 7a a beveled and laterally-disposed lug M, the disk Lbeing fixed to the shaft H by means of a set-screw N or other suitabledevice and is designed to rotate therewith.

P indicates a ring. This ring is provided on one side with a cam-face,as shown at Z, and is designed to engage with the lug M on the disk L.This ring P isalso provided at diametrically-opposite points with holesm to receive the pivot-screws Q, which take into the screw-tapped holesin the ring K, thus allowing said ring Q to vibrate upon the ring orcollar K when operated upon by the lug M of the disk L.

R indicates a reciprocating arm. This arm is connected at one end to oneside of the cam-ring P by means of a screw N or other suitable device,and its opposite end passes through a loop or eye in the seed-slide S,so that when reciprocated by the movement of the cam-ring it will imparta similar motion to the seed-slide, and consequently drop the seed fromthe seed-boxes at regulated intervals.

The shaft Il may be prevented from lateral displacement in the bearingsby means of a collar T and a suitable set-screw at one point and thedisk L at another point. The bearing-boxes f for the shaft 11 arepreferably made in sections and held together by means of screws 19,although it is obvious that boxes of any desired form may be employed.

U indicates'a lever. This lever is pivoted about midway of its length inthe seat-beam, as shown at q, and one end of said lever is pivotallyconnected by means of a bracket 1) with the rear end of theframe-section E, while the opposite end of said lever carries a pivoteddepending hook IV, designed to engage the under side of the cross-beam vof the frame A, the object being to prevent the forward section of theframe E from being raised beyond a certain point, when desired, and tohold the furrow-openers down.

The wheels I on the shaft H are provided with markers 25.

Vith a machine of this construction it will be seen that the dropping ofthe seed is automatic and dispenses with the service of a man to operateit, and it will also be seen that the seed is dropped at regularintervals without the aid of a cheek-row wire.

In operation it will be seen that as the machine is driven the shaftI-I, being fixed to the wheels I, will rotate, and with it the disk L.This movement will cause the lug M to engage the cam-face of the ring P,and, vibrating the same in its hearings, will impart a similar movementto the arm R, pivoted thereto, and this arm will in turn impart areciprocating movement to the seed-slide, thereby alternately droppingseed from the respective seedboxes and at intervals proportionate to thepitch of the cam or cam projectionin the face of the ring P, and it isobvious that in some cases a ring having a cam of greater or less pitchmight be used, according to the quantity of seed it is desired to plant.

Having described my invention, what I claim is- 1. In a corn-planter,the combination, with the main frame, of the shaft having the driving-wheels fixed thereto, the disk carrying the beveled lug and also fixedto said shaft, the hollow shaft or sleeve arranged loosely on thedrive-shaft and prevented from rotating therewith, the vibratorycam-ring pivoted on the' hollow shaft and adapted to be engaged by thelug of the disk fixed to the rotatable shaft, and the reciprocating armsecured at one end to the cam-ring and at its opposite end engaging areciprocating seed-slide, substantially as specified.

2. In a corn-planter, the combination, with the rotatable drive shaftcarrying fixed wheels, of the hollow shaft or sleeve arranged on saiddrive-shaft, said sleeve being fixed at one end and prevented fromrotation with the drive-shaft and having its opposite end threaded, thering or bearing screwed on the threaded end of said sleeve and havingdianietrically-arranged screw-tapped holes, the

cam-ring having corresponding holes, the screws pivotally connecting thecam-ring to the bearing-ring and the disk secured to the rotatable shaftand carrying a lug to engage the cam-ring, and an arm connected withsaid ring at one end and connected at its opposite end with areciprocating seed-slide, substantially as specified.

3. In a corn-planter, the combination, with the rear main frame, of theforward frame, the castings having vertical loops and connecting therespective frames in a hinged manner, the lever pivoted in the seat-beamand connected at one end with the forward frame and carrying at itsopposite end a depending hook, the axle-bearing arranged in the verticalloops of the castings and movable therein, the rotatable shaft jonrnaledin said bearings and carrying fixed drive-wheels, the hollow shaft orsleeve receiving the rotatable shaft and fixed at one end to one of theaxle-bearings, the pivoted cam-ring on the opposite end of said sleeve,the disk carrying a lateral lug and secured to the rotatable shaft, andan arm piv- CLIFFORD J.
